[scels240]

i dont know whats going on
just say im in 3rd gear n theres a stop sigh coming up
i put it in Neutral and brake but when i put it in neutral
it drops from where i was 3k rpms to a liitle below 500 and sounds like its gonna die
then like a little while after bumps back up to 700
i just did oil change yesturday from casrtol regular to castrol synthec blend (cuz its FREE for me!!!)

im having somewhat of the same problem. :( Does it do it even after your at a stop for a while? Im looking into replacing the pcv valve and checking for leaks/openings in the intake (maf related) that. Hopefully something can fix it cause it gets kinda worry some when im trying to warm up the car in the morning, and not being sure if its going to shut off or stay on.

Hehe! You don't downshift? :ddog:

I'd have to agree with WERDdabuilder on this one.

im on the same boat as you homie. i replaced the line(it had a small cut) and the idle still dips, maybe boost leak?
